Inconsistent locale files

[stefan6419846]

When looking through the locale files of this repository, I stumbled upon some inconsistencies:

• Some headers (comments) at the beginning use a project-specific template, some are empty, some are using the default template. The ones using the project-specific template have a copyright line without an author which does not really make sense.
• Some languages (like ro) are missing their compiled catalogue and only have an .po file.
• Some source files and compiled catalogues are out of sync (like da).

I recommend to use an uniform style and ensure that for every language, the compiled catalogue stays up-to-date to avoid confusion.

@stefan6419846 This may well be an issue coming from Weblate (the online translation tool we use).

Do you think you can investigate and suggest the appropriate fixes?

I can have a look at this by proposing a PR to the repository directly to unify the files. Hopefully, Weblate will be able to pick this up accordingly and use it in the future.

Regarding syncing the compiled catalogues, I am not sure. In theory, Weblate should be able to do this automatically (https://docs.weblate.org/en/latest/admin/addons.html#generate-mo-files), but it might need some initial sync for the existing state which I can have a look at.
